Here's a curve ball for you HDTV gurus. I have a Philips HDTV that I have used with the Comcast DVR for the past few years. I have received HDTV and regular cable channels through the DVR with no problem UNTIL I moved last week. After having my cable installed at my new residence (still Comcast), I get the HD channels great...problem is that the regular cable channels are screwed up. The audio is fine but the picture has gone horizontal. Can't make out anything. To make things even wierder, when I change the component in (I'm using component cables) to where I normally have my DVD player plugged in I get the normal cable channels beautifully but I can't get the HD channels!!! I had Comcast out today but he says he has no idea what the problem is. Any thoughts??? Thanks!!!
